Mac Funamizu has designed his version of what a mobile phone will look like in 2020. His answer is Trou - the “hologram projecting flexible mobile.”
Rather than using a screen with 3D projection, Mac Funamizu is sure technology will have evolved to allow for the whole screen to rise. When users answer their phones, the Trou screen will display 3D holograms.
Because of Trou’s flexible fame, Mac Funamizu says users can wear it around their wrists for easy access.
